SPECIFIGA'IEION forming part of Letters Patent No. 642,313, dated January 30, 1900.

Application filed August 19, 1899- Serial No. 727,748. (No model.)

To all whom it may concern:

Be it known that we, LEVIN FAUST and FRANK W. LINDGREN, citizens of the United States of America, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Mortising Machines, of which the following is a specification.

Our invention relates specifically to a machine for cuttinginortises for the reception of the leaves of hinges; and it consists of certain new and useful features of construction and combinations of parts hereinafter fully described, and specifically pointed out in the claim.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a side elevation of a mortising-machine embodying our improvements. Fig. 2 is a like view of the same with one-half of its frame sectioned away through the dotted line 2 2 in Fig. 3. Fig. 3 is a top plan view of the machine. Figs. at and 5 are detailed views of the mortising-chisels of the same. Figs. 6 and 7 are views of pieces of wood having Inortises out thereinto by our improved mortising-machine.

Like letters of reference indicate correspondin g parts throughout the several views.

A is the frame of the mortising-machine and is composed of a base A and a vertical column A, having a vertical central opening A Fig. 2,eXtending the entire length thereof, and is integral.

B B are respectively vertical and horizontal chisel-stock slideways, the former formed in and the latter rigidly secured-to the frame A.

G is a vertically-reciprocating chisel-stock adapted to slide in the vertical slideway B and provided with a chisel C of any desired form, here shown as being three-sided and rectangular.

D is a horizontallyreciprocating chiselstock, adapted to slide in the horizontal slideway B and provided with a chisel D of any desired form, here shown as being flat and of the ordinary form.

E is a bar connection pivoted by one end E to the vertically-reciprocating chisel-stock O by means of a pintle E and by the other end E to the horizontally reciprocating chiselstock D through the head E fast thereto by means of a pintle F is a shaft provided with a driving-pulley F and mounted in horizontal bearings F supported by the base A of the frame A.

G is an eccentric fast to the shaft F.

H is an eccentric-rod pivoted by one end H, Fig. 2, to the vertically reciprocating chisel-stock O by means of the pintle H and connected by the other end H through the eccentric-hoop II with the periphery of the eccentric G.

I is an eccentric mounted on a horizontal bearing 1 on the column A of the frame A and provided with an operating-lever I J is the bed-piece of a vertically-reciprocating carriage, now to be described, and is provided with an operating-arm J, projecting upward therefrom and at its upper end J 2 into engagement with the periphery of the eccentric I whereon it rests and whereby the entire carriage is suspended.

J 3 is the upper portion of the carriage, of which J is the bed-piece, and is vertically adj ustable on the latter by means of the screw J which passes upward therethrough into a socket J 5 in the former. The carriage, consisting of the parts J J is also provided with an inclinably-adjustable clamping-vise J. The latter consists of a horizontal leaf-like portion K, capable of being inclined downward on its hinge-joint K until it is in a vertical position, having a series of depressions K in the upper face thereof, terminating at its inner end in a wide vertical jaw K furnished with a slotted arm K pivot-jointed at K thereto, and a set-screw K passed through the slot K therein to clamp the same to' the rigid lug K on the part J 3 and provided with a sliding clamping-jaw K and a sliding setscrew carriage K having a locking-pawl K and a set-screw K for setting the jaw K against any piece of wood, as L, to secure the same against the jaw K for the purpose of having a hinge-mortise L, Figs. 6 and 7, out thereinto.

M are gage-rods projecting from the jaw K of the clamping-vise J".

M are gages capable of being secured at any desired points along the rods M by means of set-screws M N is a vertical gage adjustable by means of thethread N thereon and the corresponding thread in the hole N in the frame A, wherein it turns.

The hinge-stiles L of the various housedoors, bookcase-doors, &c., that require to be mortised for the reception of hinge-leaves, will obviously vary much in thickness. By means of the set-screw J the upperpart J 3 of the vertically-reciprocating carriage may be readily and accurately adjusted to receive stiles of any desired thickness. The leaves of hinges for which mortises are to be cut will also vary in thickness. The vertical gage N by being turned up or down accurately regulates the depth of mortises L to be out.

In cabinet and some other classes of work it frequently becomes necessary to cut mortises on stile edges that form acute or obtuse angles with the faces of such stiles. The clamping-vise J is made inclinably adjustable to adapt the machine to cut mortisesinto such stile edges.

The set-screw carriage K may be so set by means of depressions K in the parts K and the locking-pawl K as to adapt the machine to receive and out mortises into stiles of any desired width.

Our machine is operated as follows: Place a stile L on the leaf K of the clamping-vise J 6 against the jaw K Next advance the jaw K against it. Then turn the set-screw K until the stile is securely clamped therein..

Adjust the part J 3 of the vertically-reciprocating carriage and set the gage N, all as hereinbefore indicated, and supposing the driving-shaft F to be in rotation press upon the lever 1 which, acting upon the eccentric I, will, through the operating-arm J, elevate the carriage until the chisels have cut a mortise L to the depth required, as determined by the gage N.

We claim as new and desire to secure by Letters Patent- In a mortising-machine, in combination, a frame, a vertically-reciprocating chisel-stock, with its chisel, mounted therein, a horizontally reciprocating chisel-stock, with its chisel, mounted therein, abar connection pivoted, by one end, to the vertically-reciprocating chisel-stock, and by the otherend, to the horizontally-reciprocating chisel-stock, an eccentric and its driving-shaft, an eccentricrod, pivoted, by one end, to the vertically-reciprocating chisel-stock, and connected, by the other end, with the eccentric, substantially as and for the purpose specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
